无立管轻型井干预 (RLWI) 在墨西哥湾深水海底环境中进行。RLWI 的主要驱动力是降低成本和加速干预范围，以提高油井产能并防止生产延期。在 2020-2024 年期间，干预目标井面临利润率低的挑战。然而，根据 RLWI 的最初目标，候选井的财务指标仍然具有吸引力，产生了两位数的净现值和内部收益率。此外，1 至 2 年的启发式投资回收期也始终如一地实现。

Riserless light well interventions (RLWIs) were conducted within the deepwater subsea environment of the Gulf of Mexico. The main drivers for RLWI were cost reduction and acceleration of intervention scopes in order to improve well productivity and prevent production deferrals. During the period 2020–24, target wells for interventions were challenged by low margins. However, per the original objectives of RLWI, financial metrics for the candidate wells were still found to be attractive, yielding double-digit net present value and internal rate of return values. A heuristic payback period of 1 to 2 years also was consistently achieved.
